Patent

CA 2583517

The onset of activity of a first analgesic/antipyretic composition containing an analgesic/antipyretic effective amount of acetaminophen, caffeine and, optionally, aspirin is shortened by incorporating in the first composition an onset of analgesic/antipyretic activity shortening amount of at least one alkaline agent whereby a second composition is produced. The second composition being bioequivalent to the first composition but having a shorter onset of analgesic/antipyretic activity than the first composition.

Le délai d~action d~une première préparation analgésique/antipyrétique, contenant une quantité d~acétaminophène, de caféine et éventuellement d~aspirine suffisante pour induire un effet analgésique/antipyrétique, peut être réduit en incorporant dans ladite préparation une quantité d~au moins une substance alcaline suffisante pour réduire le délai d~action de ladite préparation. La seconde préparation ainsi obtenue est bioéquivalente à la première mais développe un effet analgésique/antipyrétique dans un délai plus court.
